One thought on “Climate Change — The state of the science”

Have we not already blown the 2 degree limit?
Firstly, there are some big lags in the system.
Secondly as well as the CO2 there are aerosols that mask about half the effect of the CO2, those aerosols will wash out about twelve months after we stop polluting.
Finally there are feed-backs underway that we are yet to see the full effect of, melting Arctic sea ice and melting permafrost.
